tmedicci opened a new pull request, #18941:
URL: https://github.com/apache/nuttx/pull/18941
## Summary
* arch/risc-v: Clear BSS section for RISC-V-based Espressif SoCs
* Always clear the BSS section before calling `bootloader_init`. This is
necessary because, otherwise, `bootloader_init` may fail even before
`bootloader_clear_bss_section` is called again by that function.
## Impact
Impact on user: No.
Impact on build: No.
Impact on hardware: No.
Impact on documentation: No.
Impact on security: No.
Impact on compatibility: No.
## Testing
There is no specific test for it. It is just an improvement to ensure the
firmware boots up. `ostest` can be used to test it.
### Building
```
make -j distclean
./tools/configure.sh -S esp32p4-function-ev-board:ostest
make flash ESPTOOL_PORT=/dev/ttyACM0
picocom -b 115200 /dev/ttyUSB1
```
### Running
Just run `ostest`.
### Results
```
nsh> ostest
stdio_test: write fd=1
stdio_test: Standard I/O Check: printf
stdio_test: write fd=2
